I'm in the process of changing the primary fuel filter for the first time on my 1978 H30. The existing filter is not the easiest to work with and it sounds like, from reading some of the other posts on this forum, replacing it with a Racor would be a worthwhile upgrade. A couple questions I had are: is there a particular model of Racor filter that works well with a 1 cylinder Yanmar (YSB12)? The existing filter seems to be 10 Micron so I may want to stick with that but I was curious if there were some differences in terms of rate of flow or anything else? Secondly, I was trying to disconnect the fuel hose that connects the fuel tank to the primary fuel filter. It is connected by some kind of screw-in fitting and when I try to turn it, the whole hose rotates with it. Is the section I have indicated in the red box supposed to rotate independently from the rest of the hose (view is from above)? Thanks.
